...powered circuit, connected to the following external parts:
an Arduino Pro Mini 5V 16MHz.
a HC-06 bluetooth module.
an A3144 hall effect sensor.
a 3 pin switch.
a DC motor, preferably running at 9V.
a suggested 6 pcs 1.5 V Energizer Ultimate Lithium AA batteries.
The Arduino will have a power down function. It can sleep-wakeup-sleep for weeks

Vibration sensor is to install at window, when arduino nano gpio detect (normal 2 cable vibration alarm sensor) vibrate 10ms, it will send the signal to other gpio to high for activate relay.
Note:
1. Vibration Sensor 2 Wire, normal mode is NC
2. Require Arduino Nano in sleep mode at normal time for save power, weak up by detect first vibrate,

...expert. However, I´d like to be able to make small modifications myself in the future so the software, Schematics and Layout should be in a format I can work with (KiCAD and Arduino IDE are the chosen tools).
We´ve made a stripboard prototype which partially works, and in the next step I´d like to order some production boards (maybe one to five) for

...Notification system for household.
Proposed Work: To create a LPG Gas detection system using Arduino and LPG sensors. When the LPG level is greater than certain level, the system will detect the LPG gas leakage. The system will auto turn off the valve, to control the gas flow using solenoid and Turn on the Exhaust fan to reduce the LPG concentration in

In this paper we will discuss the design and inner workings of the Onity HT lock system for hotels. Approximately ten million Onity HT locks are installed in hotels worldwide. This accounts for over half of all the installed hotel locks and can be found in approximately a third of all hotels.
We hope to reveal unique insight into the way the Onity HT system works and detail various vulnerabilitie...

Hi, I want to simualate an embedded hardware project that can be over arduino/wemos(I'll prefer wemos). I want to check the flow of current and update the status accordingly.
How I want, we can discuss it, but that's almost all about it.

Hi RegulViktor, I noticed your profile and would like to offer you my project. We can discuss any details over c...any details over chat. I can discuss the price also with you. It's a hardware project. You can simulate it first and can be given half of the price. You can then do it on Arduino hardware and we I can send you the other half of the money.

I am a Electrician and very very slow at using Eagle. I am from Bendigo Victo...stop 16Mhz (220uh & 10K) or your recommendation.
3. Remove any unused item eg. card reader.
4. Use components from Seeed studio as they have all the components in stock for Arduino Mega.
5. Design to be done in Eagle
6. Place Company Logo on PCB
7. Update silk screen

I'm looking for someone who can develop Arduino based electronics for controll of the motor pull for stringing machine for tennis racquets.
Plan is to use machnics of the Babolat VS 3002 strigning machine, but to exchange electronics which are broken with Arduino circuits.
Tension range from 18-35 kg on the wire, wire is pulled with DC motor

In this project you will implement the digital control of a DC motor with position feedback on an Arduino Uno digital controller. Form groups of three people. Hardware sets will be connected to the power supplies in the lab on the 2nd floor (B211). Motor gear ratio: 1:100, torque constant Kt: 3.2*10-3 Nm/A, resistance 2.4Ω, BEMF constant Ke: 0.03384/π

I want to read RFID c...read RFID cards and make the information available via Ethernet using Arduino for this.
We will also use the Arduino to control the activation of a relay.

...convenience. Here The “Smart doorbell System” is a sensor system purely based on Arduino / Raspberry Pi and it works with sensors. The process of developing the final project can be divided into separate by the development of different part.
Anyway the product’s brain is an Arduino and we do have a sensor system initially planning to have motion sensor for

...for Cruise Control Simulation Using Arduino. It is to simulate the BMW
Active Cruise Control System using a 4-digit 7-segment display LED (to show the car speed), a distance sensor (to sense objects ahead), an increase speed button, a decrease speed button, a set speed limit button, a resume cruise control button, and an enable cruise control button.
